Alan @ Esoundz (cust. support) is usually very promt at getting back with ANY issues. (He actually exchanged some SampleTank libraries that I wasn't happy with......instantaneously).
Synthetic, although I'm guessing that this is more of a principle thing rather than the actual problem of downloading your "paid" version, I'd still DL it and install so you can enjoy your purchase.
After Esoundz replies, you take it from there.
If you do need any help, just ask and I'd be glad to help.
